• Prepares administrative proposal documents and slide decks (contact lists, calendars, kickoff, standups, and color teams), facilitates Graphics Kickoff Sessions, leads Production Meetings, and participates in Daily Standup Meetings.
• Oversee all production and delivery activities, leading production efforts for color reviews and final proposal submissions (printing, tabs, assembly, binders, packaging, labels, delivery receipts, etc.).
• Manages war room logistics, including equipment setup, loaner laptops, stocking supplies, catering needs, and expensing invoices. Coordinates with security and IT for high-side proposal system access, guest visits, and badging, ensuring all consultants and teammates are approved and briefed prior to accessing proprietary information.

Minimum Qualifications:

• Bachelor's degree and a minimum of 6 years of related proposal coordination experience and a minimum of 6 years of proposal editing experience.
• Experience with Government proposals and the ability to analyze solicitation requirements that impact editing, formatting and production.
• Proficient in and able to apply GPO, AP, and Chicago style guides, as well as style guides used by various Government agencies and internal customers.
• Familiarity with document management systems (e.g., Teams, SharePoint, Google Drive).
• Ability to work independently with minimal supervision while managing multiple, complex tasks and projects, working quickly, accurately, and efficiently under strict deadlines.
• Excellent verbal and written communication skills, with a positive, proactive approach and the ability to explain complex issues across leadership levels.
• Willingness to work evenings or weekends as required to meet proposal deadlines.

Preferred Qualifications:

• Experience working in classified environments.
• Lead in the development and governance of enterprise templates and style guides.
